Demolishing a building is noisy and dusty, but not with this robotic water-jet robot. ERO deconstructs with high-pressure water and then sucks up the residue and separates it into aggregate, cement, and water. It then sends aggregate and filtered cement slurry separately down to the packaging unit to be contained. Clean aggregate is packed into big bags, which are labeled and sent to nearby concrete precast stations for reuse. Water is recycled back into the system. Nothing is placed in landfills or sent away for additional processing. Even the rebar is cleaned of concrete, dust, and rust and is ready to be cut and reused immediately. For more information, visit
